Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
Fortrea primate-testing lab, Vienna, Virginia, 2004–05. Most of the NHPs used are one of three species of macaques, accounting for 79% of all primates used in research in the UK, and 63% of all federally funded research grants for projects using primates in the U.S. [25] Lesser numbers of marmosets, tamarins, spider monkeys, owl monkeys, vervet monkeys, squirrel monkeys, and baboons are used ...
Rodents have been employed in biomedical experimentation from the 1650s. [1] Rodent studies up to the early 19th century were mainly physiological or toxicological.The first rodent behavioral study was carried out in 1822, a purely observational study [2], while quantitative rodent behavioral testing began in the late 19th century [1] [2].
Experiments on vertebrate animals in the European Union are since January 1, 2013. [1] [2] subject to Directive 2010/63/EU on the protection of animals used for scientific purposes, which was finalized in November 2010 and updated and replaced the Directive 86/609/EEC on the protection of Animals used for Experimental and other scientific purposes, adopted in 1986.

The fly D. melanogaster is the most widely used animal in genetic studies. This comes from the simplicity of breeding and housing the flies, which allows large numbers to be used in experiments. Molecular biology is relatively simple in these organisms and a huge variety of mutant and genetically modified flies have been developed. [7]
Researchers hope these experiments prove to be the early steps of a process that ultimately turns animals into a viable solution to the severe organ supply shortage, which leads to thousands of ...
Ferrier was a pioneer in understanding the brain and used animals to show that certain locales of the brain corresponded to bodily movement elsewhere in the body in 1873. He put these animals to sleep, and caused them to move unconsciously with a probe. Ferrier was successful, but many decried his use of animals in his experiments.
One of Pavlov’s dogs with a saliva-catch container and tube surgically implanted in its muzzle, Pavlov Museum, 2005. The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.
